(he object of my invention is to provide a strong, serviceable andinexpenslve passenger car underframe provided with continuous centersills that extend from end to end of the underframe, and cast metal endsections secured to said continuous center sills and each comprising amain end sill and a platform end sill.

Another object is to rovide a passengercar underframe in whic the mainend sill and platform end sill at each end of the underframe are formedby a castmetal member provided with pockets for receiving certainelements of the bufiing device and of the draft rigging.

Another object is to provide a passenger car underframe com risingcontinuous cen ter sills extending rom end to end of the underframe, andcast metal end sections separate and distinct from the body bolsters ofthe underframe and each comprising a main end sill, a platform end sill,and platform. longitudinal sills all integrally connected together. Andstill another object isto provide a cast metal end section for passengercar underframes that can be 40 applied easily to an underframe, eitherfor the purpose of repairing the end portion of same or for convertingan old passenger car underframe into an underframe of the type in whichthe main end sill and platform end sill are integrally connectedtogether.

Other ob]ects and desirable features of my invention will be hereinafterpointed out. I y I Figure 1' of the drawings is a top plan view of aportion of a passenger car underframe constructed'in accordance with myinvention; Fig. 2 is a vertical longitudinal sectional view taken onapproximately the line 2-2 of Fig. 1; Fig. 3 is an end elevational viewof said underframe; Fig. 4 is a transverse sectional view taken onapproximately the line 44 of Fig. 1, looking in the direction indicatedby the arrow.; and Fig. 5 1s a transverse sectional view taken onapproximately the line 5-5 of Fig. 1.

Referring to the drawin which illustrate the preferred form 0 myinvention, 1 desiigrnates continuous centensills that extend om end toend of the underframe, and 2 designatesside sills which terminate at themain end sills of theunderframe, said center sills and side sills beinof any preferred type and design and either built up or formed fromcommercially rolled members. The end portions of the underfraine areformed by cast metal members A, each of which comprises a main end sillB, a platform end sill C, and integral portions to which the continuouscenter sills 1 are rlveted or connected in any other suitable manner,the side sills 2 being connected to the main end sill B,as shown inFig. 1. The cast metal end section A preferably comprises platformlongitudinal sills D ar ranged bet-ween the main end sill B and platformend sill C and inte ally connected to same, and also an integral portionE that forms a pocket for the bulfing device, not shown, the pocketmember E being arranged between the two platform longitudinal sills 85D, as shown in Fig. 1, and lying in approximately the same horizontalplane as said longitudinal sills, as shown in Fig. 4. The portions ofthe end section A to which the center sills 1 are connected, consist ofvertically disposed webs '3 that commence at a point some distanceinwardly from the main end sill B and extend throughout the entirelength of said member A to the platform end sill C. As shown in Figs. 1,2 and 3, 95 the portions of the vertically disposed webs 3 that liebetween the main end sill B and the body bolsters of the underframe, notshown, are connected together by an integral top cover plate 4 whichpreferably mer es into a horizontally disposed flange 5 on t e upperedge of the main end sill B, thus forming a substantially invertedchannel-sha ed portion integrally connected to the main end sill B, andso proportioned that it can be slipped longitudinally between the centersills 1 of the underframe, as shown in Fig. 5, the cover plate 4 of saidortion being preferably made wide enough so that it will lap over thetop flanges of the center sills. The portions of the vertically disposedwebs 3 that lie between the main end sill B and the platform end sill Cform continuations of the portions of the vertical webs 3 that lie onthe other side of the main end sill B and which form the sidesof theinverted channel-shaped portion just described, the vertical transverseweb ofthe main end sill B being slotted to receive the continuous centersills 1 of the underframe. As shown in Figs. 2, 3 and 5, the portion ofthe end section A that projects inwardly beyond the main end sill B, isprovided with depending pockets 6 that coiiperate with certain elementsof the draft riggin not shown, said pockets 6 being arranged in a lowerhorizontal plane than the center sills 1 of the underframe and beingintegrally connected to the vertically disposed webs 3 of the. member A.The platform longitudinal sills D may be of any preferred crosssectional sha e, those herem shown having a horizontally disposed topportion that merges into the top flan e 5 of the main end sill B, andprovide on-their under sides with vertically disposed parallel ribs -orwebs 7 that are integrally connected to the platform end sill C and tothe vertical web of the main end sill B. The platform end sill G isprovided with openings for receiving the various elements of the bufiingdevice that project inwardl beyond the platform end sill, and thepatform longitudinal sills D are provided with integral perforated lugs 8that receive the stemsof the bufling device, not shown.

A car underframe of the, construction above described is exce tionallystrong and is inexpensive to'manu facture as the entire end section ofthe underframe is formed by a cast metal member which is so designedthat it can he slipped longitudinally onto the ends of the center sillswhich extend contin- -uously from end to end of the u'nderframe. Saidcast metal members are separate anddist-inct from the body bolsters ofthe under-' frame, and each of sa d'members is provided with integralportions orpocketsthat cooperate with certain elements of thebuflingdevice and of the draft rigging. The cast metal members A whichform the end sections of the 'underframe are supported throughout theirentire length by the con,- tlnuous center sills of the underframe towhich theyare securely riveted or connected in any other suitablemanner, and in view of the fact that said cast metal end sections are sodesigned that they can be'slipped onto the ends of the center sills, anunderframe of this design can be repaired quickly and 'easlly.Furthermore, such a construction makes it possible to apply'cast metalend sections to thecentersills ofan old underframe and thus convert itinto an underframe of the type in which the main end sill icast metalend section comprisin and platform end sill at each end of theunderframe are integrallypdnnected together. k

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is:

1. A passenger car underframe comprising continuous center sills, andcast metal .end sections separate and distinct from the body bolstersoflthe underframe and each comprising a main end sill, a platform endsill, and (portions, that integrally connect said sill andsaid platformendsill and main on to which the center sills are secured.
